System-Specific Server Memory

This 256GB kit is built for ThinkMate VSX-R5-760S1 and VSX-R5-540RTP workstations. It targets IT professionals and system integrators who need validated ECC registered memory for mission-critical server workloads. The modules are stress-tested for stability in enterprise environments.

4Rx4 Registered ECC Architecture

The decisive specification is the 4Rx4 registered ECC design operating at DDR4 3200 with CL22 latency. This rank configuration and registered buffer are mandatory for compatibility with the target workstation chipsets; standard unbuffered or different-rank modules will not function in these systems.

Straightforward DIMM Installation

The 288-pin RDIMMs install in minutes by seating them firmly into the motherboard slots until the retention clips engage. The most common issue is mixing these registered modules with unbuffered memory or populating slots in an order the system manual does not support, which prevents the workstation from posting.

Questions about this item

How does the DDR4-3200 speed and CL22 latency translate to real-world throughput in a ThinkMate VSX-R5 server?

The modules operate at the DDR4-3200 data rate with CL22 timing; actual throughput depends on the server's memory controller and channel population.

What does the PC4-25600 designation mean for the memory interface on this ThinkMate workstation?

PC4-25600 identifies the DDR4-3200 standard; the registered DIMM interface caps at that transfer rate when the platform runs at the rated frequency.

Will the 288-pin RDIMM form factor and 4Rx4 organisation fit the memory slots in the VSX-R5-760S1 and VSX-R5-540RTP?

Yes, the kit uses the standard 288-pin DDR4 RDIMM form factor with 4Rx4 organisation, matching the slot type used in those ThinkMate models.
